Sun Hydraulics Precision Check, Relief, and Flow Control Cartridge Valves

Product Overview: Sun Hydraulics Cartridge Valves are globally recognized for their superior reliability and unique “Floating Style” design. This versatile range covers logic functions from basic one-way check valves to sophisticated pilot-operated relief controls. This category highlights precision models: CXGD-XAN (Check Valve), RPGC-LAV/LCN (Pilot-operated Relief), FCCB-LAN (Pressure Compensated Flow Control), and CAIG-LGN/CGN (Pilot-to-open Check).

Engineered for precision control under high-pressure and high-flow conditions, these screw-in cartridges integrate seamlessly into custom manifolds. They are the premier choice for construction machinery, large injection molding machines, wind power hydraulics, and marine equipment.

Key Technical Advantages:

• Floating Construction: Allows internal components to self-center during installation, preventing spool binding caused by manifold machining tolerances and extending service life.

• Extreme Environmental Resilience: All-steel architecture with hardened internal working parts ensures high repeatability and durability in harsh environments.

• Series Precision Matrix:

  • CXGD Series: Free-flow check valves offering minimal pressure drop and perfect shut-off sealing.

  • RPGC Series: Two-stage, pilot-operated relief valves providing a smooth regulation curve, ideal for main system protection.

  • CAIG Series: Pilot-to-open check valves featuring elite load-holding capabilities and precise pilot response.

  • FCCB Series: Pressure-compensated flow control ensuring constant actuator speeds despite fluctuating load pressures.
